Projecting from the edge of the plate l0, at the topthereof,to one side of and in proximity to the convex portion,

,is an inclined supporting arm 12. having` the upper end thereofenlarged. as at l-l to 'cured the pulling members 20, 2l respecA Themember 2t) is tixedly secured, as at 22, to' one end. ol the brake bandSi, and the member 21 is tixedly secured, Ias aty 23, to the other endof the brake hand 5l. 'lhe members 20 and 21'are flexible.

' The inner end ofgthe shaft 15-has fixed therewith a collarQlw fromwhich extends, an integral otl'set crank arm 25, provided on the innerside, at the fret-.end thereof'. with an apertured enlargement 26disposed vertically. Connected to the enlargement 2li, as well asdepending therefrom is a vertically tively.

Formed integral with the rear face of the plate l0. and positioned""toseaton the top of a 'forked end 28 of the, front axle 2. is :l curvedenlargement 29. formed with a vertically disposed opening St).

The convex portion 12 seats against the curved terminal 3l of the tinesof the forked end 2S ofthe axle 2. and by thisI a rangement -the plate lshifts against' theI axle 2 when the front Wheel of thc vehict issteered.

'lhe upper end ofthe arm ft) is forn'ied with a bearin;r 3T, for supporting thel pivot. 3H, ol i bell crank lc\cr ill). One armol the lever 23!) is indicated atl vvit). and the other arm at 4l. `hearm Ilt) depends from the pivot 3S. while the arm lt1 is disposed atright angles thereto and has its louter portion 42 offset and providedwith a vertically disposed apertured enlargement 43 in alignment withthe enlargement 26. The pull bar 2 e.\' tends down through the"enlargements 2G and 43 and is connected with these latter b v thesecuringdevices 44, 45, the former abuts against the enlargement 2G undthe latte against the enlargement 43.

Pivotaltx connected, as at 46, to the lower end of the arm 4() of thebell 'crank lever 39, is a voke 4T. having connected therewith one endot an operating member 48. The other end ot the operating member 48 isconnected to theyoke 4T, carried by the arm 40, of the bell crank leverBS) ot the other brake band operating nlechanism. I

The member 4S is a cable of substantial length and travels against apair of pulleys 49, carriedby brackets 50, supported from the cross bar:3l ot' the chassis. yThe memher 4.8 `further t'avels over a pulley 52,carried by a yoke adjnstably connected to a turn blickte 54 and to thelatter is adjustably connected a stem for connection with a pullinglever G, v

The drive shaft housing of the vehicle i's indicated at. 5T, and securedtherewith is a plate 58. Yoke-shaped elements 59 are em-` ployed fortlxedly securing the plate 58 to the drive sbaft housing. The plate` 58is provided with a pivot ttt), u'pon which is secured the pull leverott. Below thepivot A60,

`the lever 5? is provided iwith a series of openings (31 for adjnstablyconnectingthe stem therewith; Above the pivot (it) the. lever 5t)provided with a series ot' openingsv62 for the purpose of adjustably connecting therewith an operating member til-i. Vfor the lever 5t?. andsaid operating member {Si} is connected to the brake lever tS-l ot' the'vehicle, and at a point intermediate the ends thereof. The pivot of thelever (34 is indicated at (35.

Secured to thc drive shaft housing 57, at the forward end thereof. by acollar Gti on other suitable itu-ans. is the pivot ti'j. of a pull lever(SS. 'The opper end of the lever ('38 is provided with a barrel (if)through which extends a bar To. having connected to each o'l its ends anoperating member Tl. and each of the members Tlisprovided for operatinga brake band `shifting mechanism 72 for a rear wheel. and such brakeband shifting mechanism vof known construction. Connected to one en d ofthe bar 70, is an operating member 725 for the pull lever (t8, and whichis connected to the brake. lever 64- at the same point at which themember 63 is intached. as imlicated at`74.
